TOaZZ whom it mciy concern: f

Be it known that I, JAMES G. MASTIN, a citizen of the United States of America, and resident of Chicago, Cook county, Illi nois, have invented a certain new and useful Improvement 1n Atomlzers, of which the 7 following is a specification. I

My invention relates to atomlzers in general;

The object of my" invention is to provide a novel form of'atomizer having provision for cutting off-the air and thus discharging a stream ofliquid alone.

For this purpose my invention contems plates broadly an atomizer having a movable valve member in which the ato'mizing action-takes place and by means of which the air can be cut ofi' and the liquid alone discharged from the outlet of the atomizer.

To this and other useful ends my invention consists in matters hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 4 tudinal Sectional View showing another formof my invention. a

As thus illustrated, my invention comprises a rotary valve member or plug A mounted to turn in a heador casing B. The said valve member A has aVT-shaped passage extending transversely therethrough to provide the three lateral and interconnected openings a, a and a These openings, it will be seen, are disposed ninety degrees apart circumferentially of said member. The casing B has three passages b, b and b ,located in such manner that they register respectively withthe openings afar, and a when the said member is in atomizing .position. With the construction shown in Fig. 1, the head or casing B is fixed on the top of a can or tank C provided with an inlet 0 for compressed air. A tube 0 leads downward from the passage 5 to the bottom of the canor tank, to receive the liquid, and

the passage 6 receives the compressed air. A, nozzle D, of any suitable ch? acter, is disposed in position to discharge the liquid member through the passage 6 of the casing. Thus the atomizing action takes place in the valve member A, when the air alldllqllld come together therein. The member A can, it will be seen, be turned to cause the openings at and a to register respectively with the passages and b and in such case the air is cut off and only the liquid escapes. Also, it will be seen that the valve can be turned to a position to cut oil the passage 6, and thus close the outlet of the atomizer. In fact, the construction is such that the member A can be turned to out off anyone of the three passages 6, b and b and connect together the other two thereof. desired, can be discharged from the can or tan In Fig. 3 the invention is shown modified to serve as a hose nozzle. The head E has passages e, e and 6 which correspond respectively to the passages b, b and b of the previous construction. The passages e and e are connected I'QSpBClJlVGlf to the liquid and air pipes F and G, and the passage 6 v is made flaring to permita direct and sprayprimary atomizing action takes place. Thus the device can be governed at will to throw either a cloud of spray or a stream of liquid alone And, moreover, the same valve can be used for entirely. closing the outlet of the device.

As indicated in Fig. 1, the pipe 0 may lead to the bottom of'the can or tank C, and in this way the air will bubble up or ri se thr6ugh the body of the liquid. Such action will s'aturatethe air with the liquid, if the latter be of a suiiiciently volatile nature,.and by; shutting off the passage 6 only this mixture of air and vapor will be discharged.

hat I claim as my invention is:

1. An atomizer comprising a movable valve member and easing therefor, having air and liquid passageswhich come together within said member, the casing having a discharge opening leading from the side of said member, opened and closed by movement of s gid member.

2. An atomizer comprising a movable valve member and casing therefor, having passages whereby the atomizing action or Thus, air alone, if

point where the air and liquid come together is within said member, said member having three lateral'opemngs which inter-commu-' nicate internally of said member, and said casing having three passages each of which registers with one of said openings when the said member is in atomizing position,

said member cutting off one of said passages and leaving the others open when adjusted within said member, means for supplying compressed air tonne of. said passages, an means for supplying liquid to the second passage, the third passage serving to discharge the air and liquid intermingled within said member, and rotation of said member directly controlling all of said passages. 4. An atomizer comprising a movable valve member and casing therefor, passages whereby point where the air and liquidcome together is within said member, said member being rotatable, and the arrangement of said passages being such that operation of said member serves to cut off one of said passages and leave the other open, to change the character of the discharge.

three passages 5. An atomizer comprising a movable valve'member and casing therefor, having whereby the atomizing action or point where the air and liquid come together is within said member, said member being rotatable, and the arrangement of said passages being such that operation of sai member serves to cut off any one of said passages and connect together the other two passages, to'permitdischarge of either the air or liquid alone.

6. An atomizer comprising a rotatable and caslng therefor having passages whereby the atomizing action or point where the air and liquid come together is within said member, said openings being disposed ninety degrees apart and in line with each other circumferentially of said member. r

7 An atomizer comprising a movable and casing therefor, having 1e atomizing action or oint where the air and liquid come together is within said member, said member being rotatable, and the arrangement of said passages being such that operation of said member serves to cut oif the air and permit the liquid to escape alone.

An atomizer comprising a movable valve member and casing therefor, having passages whereby the atomizing action or point where the air and liquid come together is Within said member, said member being rotatable, and the arrangement of said passages being such that operation of said member serves to cutoff the liquid and permit the air to escape alone.

9. An atomizer comprising a movable valve member and casmg therefor having air and-liquid outlet passages whereby the atomizing action or point where the air and liquid come together is within said member, said member being rotatable, and the arrangement of said passages being such that operation of said member serves to cut off the liquid and permitthe air to escape alone, and means :for introducing compressed air below the surface of the liquid, the air outlet passage being entirely above the surface .of the liquid, whereby the escape offihe air alone may carry with it any vapor rom said liquid. 7
